What is the "Developer Pack"?

It is a common point of confusion: Why can't I just install the regular .NET Framework?

Here is the difference:

  • The Runtime (Redistributable): This is what most users install. It allows them to run applications built on .NET 4.5.
  • The Developer Pack: This includes the Runtime, but it also includes the Targeting Pack and the SDK.

The Targeting Pack is the crucial component for developers. It contains the reference assemblies (the DLL files) that Visual Studio uses when you compile your code. Without the Targeting Pack, Visual Studio doesn't know what APIs are available in version 4.5, and your build will fail.
